i SAW-HANDLE FAS'IENER.

To all fwwmc may concern."

Be it known that I, GEORGEE. MILLER, citizen of the United States,residing at Stege, county of Contra Costa, State of California, haveinvented certain new and useful Improvements in Saw-Handle Fasteners,whereof the following is a specification.`

This invention relates to means for fastening the handles and blades ofsaws together.

In carrying out the invention I aim to provide a more simple fasteningthan has heretofore been used and one so constructed as to simplify theact of connecting and loosening the blade and handle; also to re ducethe number of fastenings. p

To these ends I make use of a single transverse bolt or pin whichengages a notch in the saw blade, and, toward the other side of theblade I make use of a longitudinal bolt or pin which is slotted toreceive the blade and provided with means for engaging the blade andwith means for drawing it tight.

In the accompanying 1 sheet of drawings I have illustrated my inventionas applied to a carpenters hand saw.

In the drawings:

Figure 1 is an elevation showing the handle and a portion of a sawblade, the handle being partially cut away and sectioned to moreperfectly show one of the fastening means.

Fig. 2 isa transverse section on the line ai, a, of Fig. 1, looking inthe direction of the arrow.

Fig. 3 is a section of the longitudinal fastening bolt showing also insectiDn the saw blade therein.

Fig. 4 is a transverse section taken on the line Z), Z), of Fig. 3.

In the figures: 1 represents a saw handle which may be of the ordinaryform, and 2 is the saw blade. 3 is a notch in the upper edge of the sawblade shown in Fig. 2 and dotted lines in Fig. 1. 4 is a bolt passingtransversely through the handle, 1, and in a position to engage thenotch, 3. 5 is a Longitudinal fastening bolt provided with a nut, 6.This bolt passes through a hole, 7 in the handle, 1. The nut, 6, restsin a notch, 8, cut in the hand hole, 9, of the handle for that purpose,so that the nut, 6, and the end of the bolt, 5, will be out of the wayof the fingers in grasping the handle.

"Thebolt, 5, is provided rwith a longitudinal slot or kerf, 10, shownmore particularly in Fig. 3. This slot is of a width to receive the sawblade, 2. 11 is a hole through the saw blade at any convenient point ofthat part which enters the slot, 10. 12 is a latch which engages thehole, 11, and is pressed into it by the spring, 13, which may befastened by a screw, as 14.

In connecting the handle to the blade, the bolt, 5, is entered in thehole, 7, and the blade is then inserted in the usual kerf in the handleprovided to receive it kand its notch, 3, engages with the bolt, 4, theblade is then swung upon the bolt, 4, as a pivot until its edge entersthe kerf, l0, in bolt, 5, and the latch, 12, engages the hole, 11, inthe blade. The bolt 5, is then pushed on through the hole, 7, and thenut, 6, applied to it and tightened, drawing the blade firmly to itsseat in the handle.

To disengage the blade and handle, the nut, 6, is first loosened orremoved and the bolt, 5, then pushed longitudinally until the latch, 12,disengages the hole, 11, in the blade, 2. The blade may then be removedfrom the handle by simply reversing the movements by which it wasapplied. When the blade is drawn tightly to its seat and the spring, 13,will be within the hole, 7, in the handle and this will act as a lock tothe latch, 12, and effectually prevent accidental disengagement.

. Having thus described my invention, and an embodiment of it, in thefull, clear and exact terms required by law, and knowing that itcomprises novel, useful and valuable improvements in the art to which itpertains, I here state that I do not wish to be limited to the preciseconstruction and arrangement of the several parts, as herein set forth,as the same may be variously modified by a skilled mechanic withoutdeparting from the spirit of the invention.

l/Vhat I claim and desire to secure by Letters Patent of the UnitedStates is the following, to wit 1. A saw handle fastening device, com-Ion said bolt` engaging automatically said hole and holding said bladeWithin said slot. 2. A savv handle fastening, comprising,

in combination with a blade and handle, a

5 slot in the back edge of the blade, a fastening bolt adapted to engagesaid slot, a longitudinal bolt near the toothed edge of the blade, saidbolt being slotted to receive the blade, said blade having a holethrough it,

and a latch applied to the bolt and adapted 10 to engage Said hole.

In testimony that I claim the foregoing I have hereto set my hand in thepresence of tWo Witnesses, this 10th day of August, 1915.
